LIGHT-FIXTURE.

Specification of Letters Patent.

Patented Dec. 6, 1921.

Application filed November 10, 1919, Serial No. 336,874. Renewed June 25, 1921. Serial No. 480,466.

T 0 all whom it may concern:

Be it known that I, ARTHUR E. /VrnnnN- HOEFT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Light-Fixtures, of which the following is a specification.

My invention relates to electric light fixtures and has particular reference to suspension supports for shades, reflectors and the like which include a series of arms, .or a spider, carrying the shade-engaging hooks that have heretofore been carried on cords, chains and the like.

The object of the present invention is to provide a shade support of this type that will dispense with the necessity of a jacket on the ordinary bulb socket where the latter is placed centrally with reference to the shade and carries said shade. For this purpose the present invention has provided a series of radial arms, a support to which said arms are pivoted and which is adapted to engage the socket against movement in one direction, and jaw or gripping portions upon said arms adapted to engage said socket against movement in the opposite direction and for the purpose of supporting the shade carried on said arms upon said socket.

Vith the above named objects in View my invention consists in the novel construction, combination and arrangement of parts, all as hereinafter described in detail, illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

In the drawing- Figure 1 is a top plan view of a shade and support therefor embodying my inven tion.

Fig. 2 is a side elevation of same.

Fig. 3 and 4 are enlarged details broken away.

In the several views 2 represents a common form of shade or bowl provided with a flange 3 to be engaged by hooks 4. These hooks are mounted on the extremities of a series of arms 5, 6 and 7 that are pivoted at 8, 9 and 10 on a ring or socket-piece 11 adapted to receive a well known form of socket 12 in which is held the usual incandescent light bulb 13. Each arm 5, 6 and 7 is preferably slightly curved as shown to Each arm is provided with a hook, grip, jaw

make it elastically adjustable to the shade.

or lug portion 14 adapted to engage the top I5 of the socket. These sockets are universally provided with an enlarged portion which provides a flange 16. This flange is engaged with the ring 11, or equivalent part, as a support against downward movement of the socket relative to said ring 11. In figure 3 is shown on an enlarged scale how the arms are engaged with the top of the socket through their hook portions 1 1. The arm 6 is shown in dotted lines swung inwardly on its pivot 9 which has swung its hook 14: outwardly out of the path of the socket entering the ring 11 from above. When the flange 16 of the socket rests against the ring 11 the arms are swung outwardly to swing the hook or jaw portions 14 inwardly and grip said top 15 of the socket. In this position two of the hooks 4c are placed under the shade flange 3 and the third hook is then sprung over the edge of the flange 3 by slightly flexing its arm or by bending two of the arms toward each other. The socket 12 is suspended from the usual overhead support by engaging the usual suspended chain or cord with an eye or ring 17 secured to the top of the socket.

I claim as my invention- 1. The combination with a lamp-socket, of a shade having a flange, a lamp-socket support, and arms pivoted on said support, said arms having jaw-portions which look said lamp socket to said lamp-socket support.

2. The combination with a lamp-socket and a shade, of a support for said socket, a series of shade supporting arms pivoted on said support and jaws upon said arms which cooperate with said support as holders of said socket.

3. The combination with an electric light 95 socket and a shade having a part or flange to be engaged by supporting lugs, of a series of arms, a socket-engaging support on which said arms are pivoted, jaw-portions on said arms which cooperate with said socket-engaging support to grip said socket, and means for supporting said shade upon said arms.

In testimony whereof I have hereunto signed my name.

ARTHUR E. WIEDENHOEFT,
